Investigators concluded that the question paper was leaked by teachers contracted to set the examination.Those named in the charge sheet include Chemistry paper-setter PV Kulkarni, Biology paper-setter Manisha Mandhare and Physics paper-setter Manisha Havaldar. Since all accused are private individuals, the CBI does not require prior prosecution sanction to proceed with the case.According to investigators, Kulkarni allegedly conducted special coaching sessions at his Pune residence in April, where leaked Chemistry questions along with answer options and correct answers were dictated to selected students. Mandhare allegedly had access to Botany and Zoology questions by April 27 and disclosed them to students during classes held at her residence.Handwritten notes recovered during the investigation allegedly matched questions that later appeared in the examination.The alleged leak prompted the NTA to cancel the original May 3 examination on May 12 after receiving an email alleging a leak and identifying overlaps between a circulated “guess paper” and the actual question paper. A re-test was conducted on June 21.The NTA declared the re-examination results on July 16. Around 1.1 million candidates qualified for nearly 137,000 MBBS seats, apart from undergraduate dental, AYUSH and allied health programmes.The CBI said further investigation is continuing and that it remains “committed to ensuring those responsible for such offences face the full legal consequences for their actions.”
